You might want to transplant to peat and sand mix. I transplanted mine and found that the ceph were grown in a peat ball. Then the nursery just place that in a biger pot with sphagnum moss. The roots did not grow into the sphagum moss. I think they do not like it. Just remove the sphagnum moss and place the whole root ball together with the peat in a bigger pot and fill up with peat + sand mix.

After mine was repotted it seem to grow row faster by giving me a few new leave.
